ESP-13U Specification V1.0

 Light-sleep used for CPU suspensive applications, like Wi-Fi switch. And while

maintaining Wi-Fi connection, If there's no data transfer, could according

to the 802.11 standard (e.g. U-APSD), turn off the Wi-Fi Modem circuit and

pause the CPU to save electricity. For example, at DTIM3per 300 ms sleep mode

andwake up 3 ms to receive AP Beacon packets, the overall average current is

about 2mA.

 Deep-sleep is used for applications that do not need to keep Wi-Fi connected all the

time , and just sending a packet after a long time, every 100s to measure temperature ,

for example, need 0.3 s ~1 s to send data every 300s wake up, and the overall average

current is much less than 1mA. The current value of 20μA is measured at 2.5V.
